服务业集聚与区域经济增长——基于省级面板数据的空间计量分析

采用物质资本集聚度、人力资本集聚度以及就业密度衡量服务业集聚水平,运用空间计量方法,研究服务业集聚对区域经济增长的影响,结果显示:我国区域经济增长呈现明显的空间集聚特征;服务业物质资本集聚水平对区域经济发展的促进作用呈弱化之势,人力资本集聚度的区域经济增长效应也由正转向负,而服务业就业密度、经济开放水平等因素发挥着越来越重要的作用。应该注重加强相邻地区间的交流与合作,形成经济互助,协调发展;同时应提高我国服务业的集聚度,充分发挥其对区域经济增长的正向促进作用。     

Social Exclusion in Britain 1991—1995

The purpose of this paper is to offer a working definition of social exclusion and to operationalize it in such a way that an initial empirical analysis of social exclusion in Britain today can be undertaken. After a brief review of conceptions of social exclusion and some of the key controversies, we operationalize one definition based on the notion of participation in five types of activity—consumption, savings, production, political and social. Using the British Household Panel Survey, indicators for participation on these dimensions are developed and analysed both cross-sectionally and longitudinally for the period 1991–5. We find strong associations between an individual's participation (or lack of it) on the five different dimensions, and on each dimension over time. However, there is no distinct group of socially excluded individuals: few are excluded on all dimensions in any one year and even fewer experience multiple exclusion for the whole period. The results support the view that treating different dimensions of exclusion separately is preferable to thinking about social exclusion in terms of one homogeneous group.

战后上海市政府应对房荒论析

抗日战争胜利后，上海市房荒严重。为了应对房荒不断升级的局面，国民党上海市政府采取了整顿租赁市场、鼓励兴建新屋和修缮破屋、营建平民住宅、举办房屋义卖等措施，这些措施对缓解房荒起了一定的作用。     

论行政救助制度的发展与完善

随着社会经济的发展和服务行政的兴起,以国家和政府为责任主体的行政救助制度已成为现代国家保障公民权利、实现社会正义的一项重要法律机制.对此,行政法应当积极回应现实的需要,拓展传统行政救助的内涵,进一步完善行政救助立法体系以及相关配套制度的建设,建立城乡一体化的救助体制.

Separable Preferences,Strategyproofness, and Decomposability

We consider strategyproof social choice functions defined over product domains. If preferences are strict orderings and separable, then strategyproof social choice functions must be decomposable provided that the domain of preferences is rich. We provide several characterization results in the case where preferences are separable only with respect to the elements of some partition of the set of components and these partitions vary across individuals. We characterize the libertarian social choice function and show that no superset of the tops separable domain admits strategyproof nondictatorial social choice functions.     

Identifying key factors in momentum in basketball games

Momentum as elaborated under a recent novel definition has been shown quantitatively to have a significant impact on basketball game outcomes. This paper makes two contributions to the analytical literature on sports momentum: (1) two aspects of the new definition are operationalized so that its practicality becomes evident; and (2) through a dimension-reduction technique (elastic net), key factors associated with momentum are identified. Both technical variables such as field goals, assists, rebounds, etc. and environmental variables such as the spectator attendance rate and player salary dispersion are considered, and the potential for useful real-time analyzes is illustrated.

Implementing the right project structure to achieve coopetitive innovation projects

This research focuses on the project structure used by coopetitors to achieve common innovation projects. Scholars have recently identified an original but complex project structure that they call the Coopetitive Project Team (CPT). However, other project structures can also be implemented by coopetitors to achieve innovation. Therefore, we address the following question: for which types of innovation projects is CPT appropriate? We argue that coopetitors need to use CPT for high-risk and high-cost projects when the aim is to develop radical innovation. CPT allows coopetitors not only to develop innovation capabilities through close resource and knowledge sharing but also to manage the risk of opportunism. Conversely, coopetitors should use another project structure, Separated Project Teams (SPTs), for low-cost and low-risk projects when the aim is to develop incremental innovation. The SPT design allows coopetitors both to achieve the goal of the project and to minimize the risk of opportunism. To confirm our assumptions, we studied the project portfolios of Airbus and Thales, two firms in the space satellite industry. Our findings confirm that coopetitors should implement CPTs to handle innovation projects that are costly, risky and highly innovative. CPTs permit the sharing of knowledge and the management of high opportunism risk, both of which are necessary to achieve radical innovation. Conversely, coopetitors rely on SPTs for low-cost projects that require a low degree of knowledge sharing, thus avoiding the risk of opportunism in achieving their incremental innovation objectives.
